39 to provide a roll a disk member 44 is` 41 being slidable in the drum11. As shown in Fig. 8, there are three apertures 46 in the inner end ofthe drum 12, and the apertures 46 are registrable with the frankfurterspaces of the frame 23 and register with the apertures 37 formed in thecap 14. A ap 46a may be provided over each of the apertures 46 to closethe same, the iiap 46a being suitably hinged to the inner end of thedrum 12 so that the ap may swing upwardly. From the foregoing, it willbe understood that the rod 42 may be connected to any one of theplungers 40 and manipulated to push a frankfurter, which may be inalignment therewith, out of the frame 23 and out of the drum 12 throughone of the apertures 46, the rod 42 being slidable in the drum 12.

It will be understood that the slot 4S in the drum 11 registers with theapertures 46 in the drum 12.

The sandwich-assembling means 20 supported on the bed 19 is locatedbetween the slot 45 and the apertures 46. As shown in Figs. 9 and l0,the sandwich-assembling means comprises a lower part indicated generallyby the numeral 47, and an upper part indicated generally by the numeral48, the parts 47 and 48 being preferably of cast metal. The part 47 iselongated and generally trough-shaped, the sides 49 thereof being cutaway at 50 intermediate their ends. The trough-shaped part 47 is open atone end and has an abutment 51 at the other end, the abutment 51 beingcut away on an arc at 52. Cooperating with the trough-shaped part 47 isthe upper part 48, the latter being a generally rectangular plate andprovided with a lug 53 at each corner thereof engageable with cornersurfaces 53a on the trough-shaped part 47 for support thereby. The platepart 48 has a top 54 extending longitudinally thereof intermediate thesides. Surrounding the top 45 on three sides thereof is a depending ange55 generally of U shape and having its legs extending to one end of theplate part 48. The outer surfaces of the legs of the ange 55 meet in aridge 55a, as shown in Fig. 10. As indicated in Figs. 7 and 8, thetrough-shaped part 47 carries pins 56 at the underside thereof, one ateach end, and the bed 19 is provided with recesses 56a to receive thepins 56, the recesses 56a being so positioned that the trough-shapedpart 47 may be aligned with any one of the apertures 46, as indicated inFig. 8. The plate part 4S may be secured to the underside of a closuremember 57 constructed of sheet metal and hinged to a bracket 58 to swingupwardly, the latter being suitably fastened to the bed 19. Two thumbscrews 9 may be provided for securing the plate part 48 to the closuremember 57, the plate part 48 having two threaded holes, one at each endof the plate member, to receive the thumb screws 59. The thumb screws 59may be passed through the closure member 57 so that the plate part 48may be aligned with any of the apertures 46, the plate part 48 alwaysbeing positioned directly over the trough-shaped part 47.

From the foregoing, it will be understood that when the rods 41 and 42are aligned with the plungers to which they are hinged, as shown in Fig.l in dotted lines, the rods 41 and 42 may be pushed into the drums 11and 12, respectively, feeding a roll and a frankfurter to thesandwich-assembling means 20. To assure alignment of the rods 41 and 42with a frankfurter and a roll, respectively, a leaf spring 60 is securedat one end thereof to the left end of the trough-shaped part 47, thespring being located in a transverse slot 61 formed in the trough shapedpart 47 and the spring 60 having a part 62 at the other end of thespring 60 engageable with any of the struts 29 of the frame 22, andmovable into the slot 61 in the trough-shaped part 47 against thepressure of the spring 60, the arrangement being such that the part 62is spring urged out of the slot 61 to resist rotation of the frames 22and 23 by engagement with any of the struts 29, the rods 41 and 42 beingaligned with a frankfurter and a roll, respectively, when the part 62 isso engaged. The part 62 is so shaped that the struts 29 ride over thepart 62 against the pressure of the spring 60 when the frames 22 and 23are rotated in either direction. It will be understood that the frames22 and 23 are fixed to the shaft 21 and are in alignment with eachother, the shaft 21 being rotatable manually by means of the knob 24.

In the operation of the device, the rod 41 is first used as describedabove to feed a roll to the sandwich-assembling means 20, the rollmoving into the trough-shaped part 47 and being opened longitudinally bythe ridge 5Sa of the flange 55. Movement of the roll may be arrested byengagement of the latter with the abutment 51 on the trough-shaped part,the sandwich-assembling means 20 comprising the trough-shaped part 47being positioned s o as to be aligned with the plunger to which the rod41 1s connected. The rod 42 connected to the plunger allgned with thesandwich-assembling means 20 is then used as described above to feed afrankfurter to the sandwichassembling means 20, the plate part 48 beingdisposed with the U-shaped depending flange 55 facing toward the frame23, the latter guiding the frankfurter as it moves into the opened roll.Movement of the frankfurter may be arrested by engagement of the latterwith the intermediate portion of the U-shaped flange 55. When thefrankfurter is in this position the sandwich is assembled. The closuremember 57 may then be opened to the position shown in Fig. 8 in dottedlines, and the sandwich lifted out of the trough-shaped member 47. Whenthe closure member is again in lowered position, the operation may berepeated after first rotating the frames 22 and 23 by the knob 24 untilthe part 62 engages the next following strut 29 of the frame 22. Thepreferred practice is to connect the rods 41 and 42 to the outermostplungers 39 and 40, respectively, the sandwichassembling means 20 beingpositioned as shown in Fig. 8, and exhausting the radially outermostrolls and frankfurters, then progressively moving the rods 41 and 42inwardly to the next plungers 39 and 40, respectively, and progressivelymoving the sandwich-assembling means 20 to the next inner position. Whenthe rolls and frankfurters are completely exhausted, the caps 13 and 14may be removed from the drums 11 and 12, respectively, as describedabove, and the frames 22 and 23 refilled, and the caps 13 and 14replaced.

A heating element may be provided in association with thesandwich-making device to warm or cook food while the latter is in thedevice. In the preferred embodiment of the invention illustrated in thedrawings, a sheet-metal water tank 63 is provided under the drum 12 andsecured thereto as by welding (see Fig. l of the drawings). Under thetank 63 is a burner unit 64 comprising a suitable fuel reservoir, theunit 64 being supported from the tank 63 by a bracket 65, the latterpreferably being welded to the tank. The drum 12 is provided with asuitable inner i11- sulating lining 66 having an opening 67 formedtherein. The opening 67 registers with an opening 67a in the drum 2 Abaffle plate 68 is located over the openings 67 and 673 and secured tothe drum 12 as by welding. The bale plate 68 is perforated to receiveone end of a conduit 69, the other end of the conduit 69 opening intothe tank 63. The tank 63 is provided with a capped intake conduit 70,and may also be provided with a drain cock 71. A pair of drain conduits72 lead through the lining 66 into the tank 63. The arrangement is suchthat heat generated by the burner 64 causes steam to be generated in thetank 63, the steam passing into the drum 12 through the conduit 69 andpassing through the perforations in the channeled member 34, warming orcooking the frankfurters in the frame 23.

From the foregoing it will be evident that the sandwich-making device ofthe invention is unitary and selfcontained, the food articles thereinbeing completely enclosed so as to be kept clean. The device is lightand compact, and therefore may be carried easily from place to place,and in this connection it is to be noted that the device may be strappedto the operators shoulders and easily operated while so supported.Another advantage of the device is that it comprises few parts and iseasily cleaned.
